A notebook computer with detachable display unit is disclosed. The notebook computer includes a main body, a hinge, and a display unit. The hinge includes an electrical connector, an elastic element, a post, and a pivot shaft. The electrical connector is connected with the elastic element. The post is combined with the pivot shaft. The pivot shaft is assembled on the main body. The display unit defines an opening therein. The display unit includes an electrical connector, an opening, and a locking mechanism. The opening is configured for receiving the post. The electrical connectors of the hinge and the display unit are configured for engaging with each other. The locking mechanism is configured for locking or detaching the connection between the display unit and the main body. The elastic element can reduce the shock that the electrical connectors suffered when the display unit is connected or disconnected to the main unit.

FIELD OF THE INVENTION

The present invention relates to a notebook computer, and particularly to a notebook computer having a structure for allowing a display unit to attach to or detach from a main body.

DESCRIPTION OF RELATED ART

Computers are in widespread use, and notebook computers in particular are getting more and more popular because of their portability. Typically, a liquid crystal display (LCD) unit of the notebook computer is fixed to the main body of the notebook computer, however recent developments have seen the introduction of notebook computers with a detachable LCD unit.

For example, U.S. Pat. No. 5,805,415 describes such notebook computer. The display unit has two posts to cooperate with two openings based on a main body, the connection of the posts and the openings are locked by two locking mechanisms based on the display unit. Edge connectors of the display unit and the main body cooperate with each other to electrically connect the display unit and the main body. However, the posts are easy damaged while the display unit is attaches to or detaches from the main body, due to forces acting on the edge connectors. The forces may damage the edge connectors. So what is needed is a notebook computer with a detachable display unit, posts for connecting the display unit and the main body are based on the main body, and the display unit or the main body is connected with electrical connectors by buffering mechanisms.

SUMMARY OF INVENTION

A detachable notebook computer is disclosed. The notebook computer includes a main body, a hinge, and a display unit. The hinge includes an electrical connector, an elastic element, a post, and a pivot shaft. The electrical connector is connected with the elastic element. The post is combined with the pivot shaft. The pivot shaft is assembled on the main body. The display unit defines an opening therein. The display unit includes an electrical connector, and a locking mechanism. The opening is configured for receiving the post. The electrical connectors of the hinge and the display unit are configured for engaging with each other. The locking mechanism is configured for locking or detaching the connection between the display unit and the main body.

Further features of the invention will be described or will become apparent in the course of the following detailed description when read in conjunction with the attached drawings, in which:

DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, a detachable notebook computer in accordance with a preferred embodiment of the present invention is shown. The notebook computer includes a main body 1, a display unit 2, and hinges 3 and 4.

Referring to FIGS. 3, 4, 5, and 6, each of the hinges 3 and 4 includes a pivot shaft 311, a post 312, two hinge covers 314 and 315, and two caps 331. The pivot shaft 311 is fitted on the main body 1 and received in a vessel formed by the two hinge covers 314 and 315. The post 312 is rotationally connected with the pivot shaft 311 and passes through the vessel formed by the two hinge covers 314 and 315. The post 312 defines a groove 313. The hinge caps 331 cover a connection part of the pivot shaft 311 and the main body 1. The hinge caps 431 cover an end of the vessel formed by the hinge covers 314 and 315 of the hinge 4.

Referring to FIGS. 3 and 4, the display unit 2 includes a top 23, a bottom 24, two side frames 51, two end frames 26, and a middle frame 25. The side frames 51, the end frames 26, and the middle frame 25 are connected correspondingly to form a frame for supporting the display unit 2. The top 23 defines two grooves 231 and two through openings 232. Each end frame 26 defines an opening 262 to receive the post 312. Furthermore, each end frame 26 defines a groove 261 leading to the opening 262.

The detachable notebook computer further includes two locking mechanisms to lock or detach the connection between the display unit 2 and the main body 1. Each locking mechanism includes a locking key 290, a locking piece 291, and a spring 292. The locking key 290 is firmly connected with the locking piece 291 and received in the groove 231 as well as the locking piece 291. The locking piece 291 is also received in the through opening 232, and further connects to the end frame 26 through the spring 292. The locking piece 291 engages with the groove 313 when the post 312 is in the opening 262.

Referring to FIGS. 4 and 6, an electrical connector 42 is assembled in the vessel formed by the hinge covers 314 and 315 of the hinge 4, and an electronic connector 22 is assembled on the middle frame 25. Furthermore, the electrical connector 42 is connected to the hinge cover 314 through two elastic elements 421.

To assemble the display unit 2 on the main body 1, firstly the two locking keys 290 are moved toward each other, thereby simultaneously moving the locking pieces 291 connected therewith. As a result, the springs 292 are connected therewith the locking pieces 291 are compressed, the posts 312 are inserted into the corresponding openings 262, and the electrical connector 42 is connected to the electrical connector 22. Due to an elasticity property of the springs 292, each spring 292 correspondingly pushes the locking keys 290 away therefrom to return to their initial forms, and thus the locking pieces 291 connected therewith are impelled to engage with grooves 313, resulting in the display unit 2 being connected to the main body 1. Moreover, the display unit 2 can then be pivotally folded into an opened and a closed position relative to the main body 1. Conversely, it is apparent that reverse steps can be used to separate the display unit 2 out from the main body 1, therefore, for simplicity, the description of the inverse steps is omitted herein.

In assembling or separating the display unit 2 on or from the main body 1, the electrical connectors 22 and 42 are subjected to shock. The elastic elements 421 can be elongated or compressed to absorb the shock. The connection between the electrical connectors 22 and 42 may be also loosened by shock causing disconnections, in such a case the elastic elements 421 can act as a means to reaffirm the connection.

It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
